IMPROVEMENT IN DETACHING HORSES.

Specification forming part of Letters Patent No. 148,152, dated March 3,1874; application filed January 7, 1874. i

To all whom it may concern:

Be it known that I, ISAAC THOMPSON, of Chicago, in the county of Cookand State of Illinois, have invented an Improvement in Devices forPreventing Horses from Running Away, of which the following is aspecification:

This invention relates to a device in the form of a winch attached tothe rear axle of a carriage, and carrying two wires or cords leadin g tothe bit-rings, and so arranged as to be wound upon said drum throughspur-gears upon the hind wheels meshing with pinions upon said drum, andthus draw back the horses head with much greater force than can beexerted upon the driving-reins. The invention consists in the peculiarconstruction and arrangement of the said drum, cords, and gears, and thedevices for. throwing the pin ions in and out of gear.

Figure l is an enlarged longitudinal vertical section of the device forthrowing the pinions in and out of gear. Fig. 2 is 'a perspective viewof the running-gear of a carriage fitted with my device.

In the drawing, A represents the rear axle of a vehicle, connected by aforked reach, B, with the fore axle 0. Dis a three-sided frame, securedunderneath the reach and axle, the open ends projecting to the rear ofthe said axle. At each end is a short standard, in which the winch E isjournaled. At each end of said drum is a pinion, a, and on the inner endof eachhub of a hind wheel is a spurgear, I). The frame D is not rigidlysecured to the axle and reach, but slides in stirrups pendent therefrom.To the front end of said frame is attached a toothed rack, c, with whichengages a geared segment, d, secured to a shaft, 0, transverselyjournaled in the reach, and having at one end a lever, j, which projectsup through a slot in the bed of the carriage. F F are wires orcords,securedat one end to the winch, the other ends being led andsecured to the rings of the bit in the horses mouth.

When the horse attempts to run away, the driver may throw forward thelever f, to bring the pinions into gear withthe spur-wheels, which thusset the winch in mot-ion, winding upon the wires or cords F, whichforcibly draw back the horses head until he is compelled to come to astandstill.

' If desired, the drum-shaft may be provided with ratchets, and the endsof the drum with spring-pawls, as shown, whereby the winch will not beunwound, to loosen the cords, it the horse backs up the vehicle.

I am aware-that a winch has been used in connection with the back axlefor the same purpose that I use my improvement, and I therefore disclaimthe invention, broadly, of a winch adapted for the purpose named; but

WVhat I do claim, and desire to secure by Letters Patent, is

'The combination, with the rear axle and reach B, of the frame 1),sliding underneath the reach, winch E, provided with cogs, which meshwith spur-gears on both wheels, toothed rack c, and segment cl, securedto a shaft, 0, all constructed to operate substantially as described.
